I believe this stuff is measured in ppm (parts per million) or some such thing. That being said, once it hits the outside air, it disperses, or breaks up into the surrounding atmosphere. Unless someone has their head in front of your exhaust fan, I doubt there will be any measurable disaster.
I have this "theory", that the most dangerous time handling 2 component materials is during the mixing process. I've seen guys (with no mask) standing over a quart can,....dumping in the hardener and stirring,.....with their nose directly above the container!!!!! At that point, the ppm is most likely at the greatest level.
All that being said, commercial booths usually only filter out the solids. The crap your filter collects. The fumes go right out the stack and into the air we all breath. Scarey. Stu
